A foreign plane has appeared at North Korea’s main capital airport after apparently hiding its location data, according to NK Pro analysis, in a possible sign that military exchanges with Russia are continuing in the new year. 

Planet Labs satellite imagery shows 19 planes at Pyongyang International Airport just before noon Wednesday — one more than the 18 known aircraft of national carrier Air Koryo that are typically parked there.

The plane appeared to be at least 165 feet (50 meters) long, though its precise measurements are unknown since the imagery is not high-resolution. 

No foreign airlines
